MUSIC-LEAF TIIRNER.

Application filed October 4, 1915.

To all whom it may camera.-

Be it known that I, EDWARD J. HAWKINS, a citizen of the United States,residing at Solvay, in the county of Onondaga and State of New York,have invented certain new and useful Improvements in Music- LeafTurners, of which the following is a specification.

The present invention relates to improved music leaf turners designedfor turning sheet music and operated by pedal mechanism.

The primary object of the invention is the provision of a device of thischaracter that is simple in construction and operation, but eflicient inperforming its functions.

The device is designed to be adjustable for different conditions, inorder that the music rack, of which the leaf-turner forms a co-actingelement, may be located in desired position above the key board of thepiano or organ with which the device is utilized. By theutilization ofpedal actuated instrumentalities, I am enabled to operate the leafturner and permit the player or artist to use the hands freely forplaying purposes only. Provision also is made for turning back one ormore leaves of music when desirable or necessary, without recourse tothe use of the hands, this being ac-, complished by an auxiliary pedaldevice.

The invention consists in certain novel combinations and arrangements ofparts as will be hereinafter more fully pointed out and claimed.

In the accompanying drawings I have illustrated one complete example ofthe physical embodiment of my invention and a slight modificationthereof, constructed according to the best mode I have so far devisedfor the application of the principles of my invention, but it will beunderstood that changes involving shapes and sizes of parts andcolorable alterations are contemplated as within the scope of my claims.

Figure 1 is a side elevation of the device embodying my invention, theseparated parts of the device being closed up for-convenience ofillustration. Fig. 2 is a top plan view of Fig. 1. Fig. 3 is a frontelevation of the device of Fig. 1, showing the pedal board and the musicrack and leaf turner. Fig. 4 illustrates the three spring operatedsprocket wheels, one for each leaf turner when three are used. Fig. 5 isa side view of the spring wheel at the left in Fig. 4,

showing the spring in its casing and attached to the wheel shaft. Fi 6is a sectional view of the device of F 1g. 5 on line 6 6. Fig. 7 is asectional detail view of the bearing head of Fig. 3. Fig. 8 illustratesthe three locking latches for their respective pedals, and the returnpedal slide rod co-acting therewith. Fig, 9 shows a modified form ofhead for the leaf turner. Fig. 10 is a sectional view of the head ofFig. 9.

In the preferred embodiment of my invention as illustrated in thedrawings I employ a music rack or board 1 of convenient and proper sizeto be located in suitable position over the key board of the instrument,and suspended, vertically, by means of its bracket rod 2 which issupported in the bushing or head 3 of the swivel plate 4..

The board or rack 1 is equipped with the usual bottom ledge 5 and thepairs of spring retaining clamps or clips 6 and 7 for holding the frontand back pages of the music to the rack 1.

The rack may be supported from a suit able portion of the piano, or ifused as a portion of a music stand, it may be supported from a wall. Inany event the swivel plate 4 is adjustably secured to the adjustableslide plate or extension 8 through the pivot bolt 9 by which the swivelplate and slide plate are held, and the circular slot 10 in the plate 4and set screw 11 which passes through the slot and is threaded in theend of the slide plate 8. By this connection it will be seen that themusic rack may be adjusted on the pivot point 9 in order to vary theinclination of the music rack with rela tion to the vertical.

The adjustable slide or extension plate 8 is perforated to accommodatetwo bolts or screws 12. 12 which are utilized to secure the extensionplate 8 in desired relation with the complementary plate 13 which isalso slotted as at 13 to accommodate the screws 12, 12 and overlaps theadjoining end of the plate 8. This arrangement of parts permits of anadjustment of the music rack toward or away from its supporting wall orother object, and enables the artist or musician to adjust the rack tohis wishes.

A further adjustment of the device is accomplished through theconnection between the arm 13 and the bracket 14 by means of which themusic rack is supported from a stationary member as 15 by screws 16. Thebracket 14 is fashioned with a swivel head 17 slotted 18 and pivotallyconnected with the arm 13 by the bolt 19. Thus this swivel connectionmay co-act with the swivel connection at the free end of the extensiblearms 18 and 8, and when in adjusted position the parts 13 and 17 may besecured together by the screw in the drawings T have illustrated thedevice as equipped with three leaf turners A, B, C, and it will be seenthat these comprise angular arms each provided with the usual springclamps 21, 22, provided with a release lever 22 to hold the leaf andinsure its quick and proper movement when the leaf is turned. Theleaf-turners are each fashioned with a shank or arm 23, 24-, 25respectively and these respective arms are fixed to bushings 26, 27, 28of their sprocket wheels 29, 30, 31. These bushings and sprocket wheelsare rotatable on the bracket rod or shaft 2 which is threaded at 2 forthe clamp nuts for holding the revoluble members on the shaft 2. Each ofthese sprocket wheels is revolved by a section of chain as 33, 8%,passed over the respective wheels and each chain has attached at itsends a cord or cable as 36, 37, 38, passing over guide pulleys 39 andtO, down to the pedal mechanism that is located in convenient positionto be actuated by the foot of the musician.

Each pedal device includes a sprocket wheel as it, 4-2, 4:3 and asection of chain as 44 is passed over each sprocket and connected to theends of its individual cord or cable.

The sprockets ll, 42, i3 are spring wound 2'. 6. each is equipped with aspring as L5, fastened. at one end in its casing i6 and at its other endto the shaft t? of the sprocket wheels. Each of these shafts has a pedalas as, L9, 50, formed each with a hook 51, for engaging the shaft andsaid pedals coact with a pivoted latch 53, 5a and 55, which have the camface 52 and are pivoted at 56 on the board 57, the springs 56 beingprovided for retaining the latches in normal position. This cover board57 is slotted so that the hooked ends of the pedals may protrude fromthe interior, and it will be apparent "hat by depressing the pedal 48for instance by foot power, the cam face 52 will be forced aside toallow the pedal to pass below the straight underside of the latch 53,when the spring 56 will return the latch and thus retain the pedal indownward or depressed position, this depressing of the pedal revolvesthe sprocket wheel ll, winding or tightening the spring do, which returns the parts to normal position as is hereinafter set forth, andthrough the chain and cord connections the leaf turner is folded orswung over to turn the leaf of music. The three pedals are operatedsuccessively and their individual actions are similar A fourth pedal isemployed to return the latches to normal position. This pedal is pivotedon the cover board 57 at 59 and connected to a slide bar 60 at 61; Theslide bar is movable in bearings 62 and is formed with series of threelugs 63 adapted to impinge against the lower end of the latches. Whenthe pedal 58 is pressed down, the movement of the slide bar 60 to theright, see Fig. 8, moves all of the latches on their pivots 56,releasing the pedals 4:8, 49 and and allowing the springs 45 to unwind,revolving the sprocket wheels ll, 42 and backward, and through the chainand cord connections return the leaf turners to normal position, andwhen pressure is removed from the pedal the spring restores the latchesto their normal position. Each latch is provided with an individual pinas 64; by means of which it may be swung on its pivot and returned tonormal position.

In the modified forms of the invention in Figs. 9 and 10 the arms 25 24B23 are ar ranged below the head 3 instead of above the head, to makemore compact arrangement of parts which is sometimes desirable.
